Using minoxidil 5 % after a FUE - 1 month an 7 days after, but still redness on scalp? (photo)

It is best to ask your surgeon about post operative care as each doctor has their unique regimen. In general, minoxidil is not required after surgery.

Minoxidil should be fine to use past one month, provided that the healing process of your FUE has been fairly normal. A little irritation is a common side effect of it and if it doesn't bother you then it's nothing to worry about. But talking to your doctor about whether it's safe to start using it again is always encouraged.

It is advised to use Minoxidil after the healing process will be completed and  all scabs are  gone . I tell my patients to start Minoxidil 3 weeks after their hair surgery. As it was mentioned below healing process may differ from patient to patient . It is always a good idea to consult with your surgeon for post op care 

You can resume minoxidil after the transplant when all the scabs are gone.  Everyone heals differently and redness often persists at one month.  Use the minoxidil if its comfortable for you.

Minoxidil is an irritant so using it will cause redness and itchiness that you may have to deal with. It will not help you grow the transplanted hair.
